Oil coolers usually have female ports, so they are always supplied with adapters in place for the connection you want. AN, BSP and metric are equally common, a dealer should be able to supply what you need.

That's good info, thanks. I had new oil lines made for the engine, but can't find the receipt and forgot what fittings they are. They're duplicates of what was there so I'm guessing some type of BSP...anyone know what these cars came with for sure?
